Somewhere north of Seventy as I have lost count, most don't run. I'm getting ready to sell off several of them as I don't think I'll ever get the time to get to all of them and can put the money to better use. A/C, Ariens, Bantam, Bolens, Bush Hog, Case, IH, Ford, Jacobsen, John Deere, M/F, MTD, Midland, Minni-Mo, Montgomery Wards, Simplicity and Wheel Horse. I think that's all the different brands I own.
